Well, they're kinda fun to put together.....
They've all started right up, and they make sawdust.....or chips, or whatever you wanna call it.
Definitely not as refined as real saws, but they mostly work.....for how long I don't know....
I recently bought a neo tech 543xp clone.....it seized up on the second tank of fuel......the only saw I've ever seized in 30 plus years of running powersaws...
I think the clones are a viable option for people that need a bigger saw on occasion, but want to spend the dough for a OEM saw.
